      go/types: fix type-checking of shift expressions · 3a9fcc45
      Robert Griesemer authored
      Completely rethought shift expression type checking.
      Instead of attempting to type-check them eagerly, now
      delay the checking of untyped constant lhs in non-
      constant shifts until the final expression type
      becomes clear. Once it is clear, update the respective
      expression tree with the final (not untyped) type and
      check respective shift lhs' where necessary.
      
      This also cleans up another conundrum: How to report
      the type of untyped constants as it changes from
      untyped to typed. Now, Context.Expr is only called
      for an expresion x once x has received its final
      (not untyped) type (for constant initializers, the
      final type may still be untyped).
      
      With this CL all remaining std lib packages that
      did not typecheck due to shift errors pass now.
      
      TODO: There's a lot of residual stuff that needs
      to be cleaned up but with this CL all tests pass
      now.

      runtime: refactor Syscall benchmark · 38d4d3c6
      Dmitriy Vyukov authored
      And add a benchmark where #goroutines>GOMAXPROCS,
      because it's the most interesting case.
